Optically stimulated luminescence (OSL) thermochronometry is a method for estimating the thermal histories in the ultra-low-temperature domain less than several tens °C. This method is capable of reconstructing the exhumation histories of a period over which rocks are exhumed several hundred meters assuming general geothermal structure. Thus it is expected to be used for unraveling tectonic activities over 104–105 year timescale. We introduce the principle and closure temperature of OSL thermochronometry, the latest method of thermal history analyses, and case studies of OSL thermochronology.

Key words: optically stimulated luminescence (OSL); infrared stimulated luminescence (IRSL); quartz; feldspar; thermochronology; thermal history; Quaternary; exhumation
